Which of the following reactions would you predict to have the largest
orientation factor?

1 NH3 (g) + BCl3 (g) -> H3N-BCl3 (g)

2 H (g) + Cl (g) -> HCl (g)

3 NOF (g) + NOF (g) -> 2NO (g) + F2 (g)

4 Br2 (g) + H2C=CH2 (g) -> H2BrC-CBrH 2 (g)

5 All of these reactions should have nearly identical orientation
factors.

My guess #2

==================================================

What is the vapor pressure of aqueous solution containing 10% ethylene
glycol (62.067g/mol) at 25 c

PH2O=23.5 torr at 25 C

1. 25.1torr

2. 21.9torr

3. 23.5torr

4. 18.9torr

5. .761 torr

My guesswork

Mass ethylene glycol = 10 g
moles = 10/ 62 = 0.161

mass water = 90 g
moles = 90 / 18 = 5

mole fraction water = 5 / 5 + 0.161 =0.969

p = 24.3 x 0.969 = 23.5 torr

======================================================

If the concentration of CO2 is 2.90 g of CO2 per 1.00 L of soft
drink when bottled under 2.0 atm of CO2 pressure, what will be the
concentration of the CO2 in the drink after it has been opened and
left to come to equilibrium with the atmosphere which has a CO2
partial pressure of 3.0 x 10-4 atm?
